description The present invention provides an ultrasonic imaging device capable of generating highly accurate image information of a bonding interface of an object by generating pixelized information using a waveform from which noise is removed. An ultrasonic imaging device 100 irradiates an object formed by laminating a plurality of layers with an ultrasonic wave to obtain a reflected wave of a bonding interface of the object, and generates an image of the bonding interface based on signal intensity of the reflected wave. The ultrasonic imaging device 100 includes: a matching processing unit 56 for correcting a phase shift of a second reflected wave from a second irradiation point in the object with respect to a first reflected wave from a first irradiation point in the object; and a pixelized information generation processing unit (averaging processing unit) 57 for removing noise from the first reflected wave based on the first reflected wave and the second reflected wave after phase correction, and generating pixelize
